where to sign

i have recently got a creit card, it tells me to sign at the back of my card, now should i remove the white tape on which the number is printed or should i sign on the white tape,
this card was given to me by a pharmaceutical company it was given free of cost, now can the card company ask me to pay the annual fees of that card

If you're looking at the back of the card, there is be a white 'strip' just above the embossed numbers. Mine has the last four digits of my account number, plus three 'verification' numbers. There is where you need to sign your name (don't try to remove it).

If I may ask, why did the phamaceutical company give you a credit card? If they're your employer, they will usually pay the fees. Please provide more details, and I'll try to help.
